To all whomttmay concern:

Be 1t knownthat I, MICHAEL BANDRINCA,

a citizen of the United States, residing at- Chicago, inthe county ofCook and Stateoie l Illinois, have invented certain new and use fulImprovementsin Squeegeesg and I do hereby deolare'the followin to be afull, clear, and exact description o the invention,

such as will enable -others skilled in the art to which it appertains tomake and use the- ...This inveneonreiaesm@ meow. fifiii? ers, and more`especially to those of that type known as squeegees, and the object ofthe same is to produce a device of this kind whose working edge is madeof several plies or laminations, so that when one becomes Worn orhardened' in usage, it maybe torn off or Cut olf to expose the nextlamination.

Aurther object is to produce a device of this character where thelaminations or strips grow successively narrower or are' stepped,.sothat "the tool can be inverted at times when itis desired to give anextremely fine finish to the surface-beingl treated.

With this and other objects ink view the y'invention comprises detailsof construction as set forth in the following specification andy shownin the drawings wl :rein- Figure l is a perspective view of this windowcleaner ready for use. Fig. 2 is an end elevation of the head `of theimplement inverted, showing howy it may be-employed so that'the forwardedges of all ,its strips f Contact withfthe glass. Fig.. Sis a bottomplan view of part of the head of the tool, showing the lowermost orwidest strip as being removed.

As usual withv thev devices of this kind an ordinaryv long, Woodenhandle@ H, Vcarries a errule, F, at its upper end, the saine beingsecured in avsutable manner as by screws S to a headfM'whiCh may well bea piece of wooden molding .of the desired'.

tom of a rabbet formed along the under side ofthe head M. Any suitablemeans may be employed for holding said rear edges in place, but as shownherein Iv use a metal strip 7 which underlies the rear edge .of thewidest rubber strip 5 and pass screws or nails 8 upward through themetal strip and allthe .rubber strips into the head M.

: While I have stated that the strips consti- A tuting the active edgeof the implement are ,Qfwrubber, I do-not wish to be limited strictlyfthel'eto, as, rubber vcomposition or other ma' terialmight be employed.

It is essential, however, to the gist of the present invention that thelaminations or vstrips grow successively wider so that they will presenta working edge which is stepped, as perhaps best seen in Figs. 1 and 2.This makes the lowermost and widest strip 5 quite flexible, but it isprevented from flexing upward unduly7 by the presence of the otherVstrips above it.

In' use, the operator who is washing a window commonly wets it andsponges it with a suitable tool carried by a long handle so that he canreach the window from the ground. The squeegee is then brought into use,and the front edge of the lower- `most strip pressed against the panenear the top of the latter and wiped slowly down-c ward over thewindow-pane as well understood. This is repeated clear across the pane,with the result that the moisture is wiped oil and the surface is leftclean and dry. It may be desirable in some cases, with some kinds ofglass or under certain -conditions of the-weather, to invert orreverseithe head M of the squeegee and wipe the working edges of all thestrips downward over the pane as seen in Fig. 2; and ths will give anextremely fine finish to the o JA In time the corner of the widest strip5 will become wornor possibly broken or torn 'by long use oit the tol,and the operator may then tear or cut oli this strip 5 as seen Ain Fig.3. IIe may either run 4a knife along the edge ofthe metallic strip 7 andcut the rubber strip 5 partly through and then tear it thel rest of theway andV remove it entirely'; or'if this rubber strip be thin enough hecan simply tear it off if it be started at one end. Its removal leavesthe second strip 4 projecting beyond the`working edges ofl the stripsabove it and tlfieY implement Lemay "f yet be used successfully for sometime,"ar`te"r which this strip also may be removed when it becomes Wornor damaged, and then the Anextstrip 3,. and so. on. It is quite possibleY, that a strip or strips could be replaced others as by removing thenails or screws 8 and metal strip 7 and substituting new rubi' berstrips for those which are damaged.

The gist of the invention, however, lies in making the Working edge orrbber portion of the squeegee in laminations or strips Whose rear edgesare secured to the head and whose front edges are disconnected from anddisposed in stepped relation to each other, the uppermost strip beingthe I narrowest yand the lowermost the widest.

Modifications in andA amplitications of this general idea may beresorted-to Without departing from the principle of the invention, |Theproportions of parts nre obfviously immaterial.

What isv claimed as new is:

' MA. squeegee comprising a handle, a head having arabbet, :rn activeedge composed of strips of flexible material of diii'erent Widths, theirrear edges standing flush within the saidrabbet and their front edgesdisposed in stepped relation to leach other, the.

lowermost strip being the Widest, a metallic strip underlying theseflexible strips near their rear edges, and fastening devices pass in gup through the metallic strip and the 1 flexible strips into said head.

In testimony whereof I afiix my signature in presence of two witnesses.
